When creating nd_namespace_blk, its uuid is copied from nd_label->uuid.
In case the memory allocation fails, it goes to the error branch.
This check is better to be done immediately after memory allocation,
while current implementation does this after assigning claim_class.
This patch moves the check immediately after uuid allocation.
